1994 BUICK CENTURY wiring

Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to
your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left.
To move the trailer to the right, move your
hand to the right. Always back up slowly and,
if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky
or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green arrows
on your instrument panel
will flash whenever
you signal
a turn or lane change. Properly hooked up,
the trailer lights
will also flash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel
will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may
think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure
the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and no longer work well.
On a long
uphill grade, shift down and reduce your
speed to around 45
mph (70 km/h) to reduce the
possibility
of engine and transaxle overheating.
If you are towing a trailer that weighs more than 1,000
pounds (450
kg) and you have an automatic transaxle
with Overdrive, you may prefer to drive in “D” instead
of Overdrive.
An overdrive transmission is required if
towing a trailer more than 1,000 pounds (450 kg).

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your Buick
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered
by your
warranty. Some add-on electrical equipment can
keep other components from working
as they
should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Buick, see “Servicing
Your Air Bag-Equipped Buick” in the Index.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by
a combination of fuses, circuit breakers,
and fusible thermal links
in the wiring itself. This
greatly reduces the chance of fires caused by electrical
problems.
The fuse panel is located inside the glove box,
on the
left side.
To change a fuse, open the glove box. Pull down on the
fuse panel latch and open the door. Pull the fuse straight
out.

Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
Headlights
The headlight wiring is protected by a circuit breaker in
the light switch. An electrical overload will cause the
lights
to go on and off or, in some cases, to remain off. If
this happens, have your headlight system checked right
away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse.
If the motor overheats due to heavy snow, etc.,
the wiper will stop until the motor cools.
If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Window
Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting
the circuit until the problem is fixed.
Cigarette Lighter Fuse and Safety Belt Fuse
These fuses are located behind the glove box. The fuse
holders are taped together with gray tape.
Other Fuses
The Safety Belt/Chime (ICAM) Module fuse and the
Remote Lock Control fuse are located behind the fuse
block, above the hush panel.
The Fuel Pump and
ECM fuses are located under the
hood.
